NEET BIOLOGY

Detailed explanation-1: -They not only lack vascular tissues; they also lack true leaves, seeds, and flowers. Instead of roots, they have hair-like rhizoids to anchor them to the ground and to absorb water and minerals (see Figure below).

Detailed explanation-2: -Bryophytes are a group of nonvascular plants that includes mosses, liverworts, and hornworts. Rhizoids are the tiny structures that stick out from the roots of bryophytes. Rhizoids absorb water and nutrients from the soil through the process of capillary action.

Detailed explanation-3: -Mosses and liverworts are small, primitive, non-vascular plants. They lack the conductive tissue most plants use to transport water and nutrients. Instead, moisture is absorbed directly into cells by osmosis.

Detailed explanation-4: -Nonvascular plants are called bryophytes. Nonvascular plants include liverworts, hornworts, and mosses. They lack roots, stems, and leaves. Nonvascular plants are low-growing, reproduce with spores, and need a moist habitat.

Detailed explanation-5: -Mosses (Bryophyta) – Found in dense clumps allowing them to retain moisture. They are larger, coarser non-vascular plants possessing multicellular rhizoids which are more like roots. Also, they have small photosynthetic structures resembling leaves surrounding a stem-like structure found at the centre.
